General CommentTo me, it seems that they are trying to say that the urge to kill is hidden in all human beings, even if a lot of us might deny it (You believe killing might be hard/But where are all the dead coming from).
Then, judging from the rest of the song, this urge might be more specific towards one's spouse or a sexual partner...

General CommentWell, it looks like it could be about sex, till you realise the German 'ihr' ('you') is plural, then it looks a lot less likely. Apart from sex, the bed seems to symbolise innocence or unconsciousness. The line "Wollt ihr mit Haut und Haaren untergehen?" (here translated "Do you want to totally go under") leaves out a potential double meaning too - 'mit Haut und Haaren' does mean 'completely', but is literally 'with skin and hair', and 'untergehen' is a euphemism for 'to perish/end'. The 'doch' that comes in twice really isn't translatable, but does give a sense of 'after all' ('you do want to stick the dagger in the sheets, after all'), so paphan could be right.

The line that confuses me is 'ihr meint euch darf die Unschuld küssen', translated correctly but ambiguously as 'You think innocence may kiss you'. This implies innocence might kiss the person in English, but in German it really means innocence is permitted to kiss the person, with 'ihr meint...' obviously negating that - innocence isn't allowed to kiss this person. Perhaps a murderer who is begging for forgiveness but can't seem to keep away from these thoughts?

The only two lines that don't seem obvious on this train of thought are 'Sex ist eine Schlacht / Liebe ist Krieg'. Any thoughts?

My idea here is that the killing isn't literal - it could mean emotional torture through arguments or bad times or people falling out. The two lines quoted above could be that it's easier to do this with someone if you like them, and the more you like them the easier it is and the more it hurts in the end. Well, just a thought.

General Commentjust a question my german is a bit rough but doesnt it say "ihr wollt doch auch den Dolch ins Laken stecken, ihr wollt doch auch das Blut vom Degen lecken" which i thought translated to "you want to stick the dagger in the sheet as well, you want to also lick the blood from the sword" talking about a sword in the second line not a dagger but i may be wrong..

General Comment=Filth=:
Dolch = dagger
Degen = technically means 'epee' but is also used for 'sword' in general

billywoods1: 'ihr' might be addressing humanity in general, condemning its thirst for blood. To me, "ihr denkt euch darf die Unschuld küssen" means that the people who are addressed here believe that they are innocent regarding "all the dead" in the world, but everybody is responsible for the deaths that occur, directly or indirectly. If you don't try to prevent someone's murder, can innocence nevertheless "kiss you", even though you didn't personally kill that person?

General CommentI think this song is about someone whose lover (wife, girlfriend?) has left them for someone else, and they fantasize about surprising the new and happy couple in their bed, stabbing them and setting the bed on fire -- not so much out of desire to cover evidence, but out of sheer outrage and a maniacal desire to destroy all there is about the couple. I think the rather bizarre line about licking the dagger might have possibly come up mainly for rhyming purposes, but was used because it keeps an image of someone who has completely lost their mind doing bizarre things in rage.
It is also possible the man is considering setting his own bed that he shared with his lost girl aflame and then killing himself with a dagger.
